Why Does Crying Make Your Nose Run?哭的时候为什么会流鼻涕?

When you burst out crying, you expect the bleary red eyes and the rivers of tears that stream down your cheeks. But on top of all that, your nose starts to run like a faucet¹. Why does this happen? What’s the connection between crying and a runny nose?
当你放声大哭时，朦胧的红眼睛以及泉涌般的泪水沿着面颊滑落是预料之中的事。除此之外，你会开始流鼻涕。为什么会出现这种情况？哭和流鼻涕之间又有什么联系呢？

Where Do Tears Come From?
眼泪从何而来？

Tears come from tear glands² located just over the eye, behind the bone. As tears rinse³ down over your eye, they collect at the rims⁴ of your lower eyelids⁶, where some may overflow⁷ and stream down your cheeks.
眼泪是由位于眼骨后的泪腺分泌的。当泪水被分泌出，他们便贮藏在下眼睑边缘，一部分眼泪溢出眼睛沿脸颊流下。

But that’s not the only escape route for overflowing⁸ tears. If you look very closely at the inside of your eyelid⁵, right near your nose, you’ll see a tiny little hole. You might need to gently pull your eyelid down to see it, because it’s on the inner edge of the eyelid, resting against the eye.
但那并不是眼泪流出来的唯一路径。如果你仔细观察眼睑内侧靠近鼻子的地方，你会看到一个极其微小的洞。你可能需要轻拉眼睑才能看到这个小洞，因为它位于靠近眼睛的眼睑内侧。

River Tears
泪流成河

These little holes, on the upper and lower eyelids of both eyes, serve as drains and lead into canals that run through grooves⁹ in the bones of the face and eventually empty into the nose. Even when you’re not crying, some of the normal, everyday tears that moisten and clean your eyes drain out through this secret passageway into the nose, but it’s such a small amount that you don’t notice it.
这些小洞位于双眼的上下眼睑，它们发挥着排水管的作用，引导泪水沿着脸骨的凹槽流下并最终流入鼻子。即使你不哭的时候，每天也会有一些正常产生的、用以湿润和清洁眼睛的眼泪通过这个秘密通道流到鼻子里，只不过它们数量太少你察觉不到而已。

When the tears really start to gush¹⁰, however, this unnoticeable trickle¹¹ turns into a river. As the tears make their way down through the nose, they moisten and loosen other secretions¹² on the way. And that’s when you reach for a tissue!
 当眼泪喷涌而出的时候，这些平时察觉不到的小泪滴便汇流成河。在泪水流入鼻子的同时，它们在沿途还起到湿润和疏松其它分泌物的作用，这时候，你就需要纸巾擦拭了。
